Device Switching - One for All EXTENDER A1 FOR URC-7780 Instructions Manual

is 1 through 12. The 73rd is X_CANCEL. Prefix letter X is explained in section 8. The other five letters
select a button grouping and assign it to Device n.
As an example, suppose that we have set up four devices
Device 1 = TV, Device 2 = SAT, Device 3 = RCV, Device 4 = DVD.
and have set VPT On and VPT Device to Device 3. Then SAT will have the following defaults:
C = Device 2, T = Device 2, V = Device 3, M = Device 2, A = Device 1, O = Device 2.
We want to change the Transport buttons to DVD and take the SAT device out of volume lock. Then we
create the macro
Note that we are assigning the Volume grouping to the device of the bound key. This has the effect of
removing the device from Volume Lock but equally we could have reassigned the Volume grouping to
any other device, so this gives greater flexibility than merely turning Volume Lock on or off for a
particular device.
It is possible to view which device is active for any button. If it is other than the device currently selected
on the LCD screen, when you hold down a button then the device displayed in the centre of line 2 of the
LCD screen changes to that of the active device. So in the above example, if SAT is selected on the LCD,
pressing and holding the Play button will change SAT to DVD until you release the button. This works,
of course, also for the default assignments, so pressing 16:9 will change SAT to TV. This feature
considers the Record key, which needs to be pressed twice to have an effect, to be held throughout from
its first press to its second. So the first press will change the centre device to that of the Transport
grouping and it will remain changed until you press Record again, or any other key for that matter, but if
it is a different key then Record will not have taken effect.

6. Device switching

The keys Dev1 through Dev12 are also available as keys that can be included in a macro. You could, for
example, set up a macro
The effect of Devn as a key in a macro is exactly the same as if that device had been selected through
scrolling the LCD. It will, indeed, change the LCD display to show Devn as the selected device and will
include any permanent reassignments of button groupings made as explained in section 4. So with the
setup described in that section, pressing key A will switch the LCD display to SAT and assign the button
groups as follows:
C = Device 2, T = Device 4, V = Device 2, M = Device 1, A = Device 1, O = Device 2.
This is an example of a nested macro. After the default reassignment made by the Dev2 key it then runs
the Dev2 macro to make the original reassignments, followed by the further reassignment by the
additional M_DEV1 key included in the key A macro.
Note that section 5 did not provide any means of changing the assignment of the Other buttons. It is not
possible to do so, this group is taken as characterising the device. If you need two devices with the same
assignment of the Other group, however, this device switching mechanism allows you to achieve it
through a button press. With the setup just described, selecting SAT through the LCD and through
pressing button A give two different Home Theatre settings with the same Other group assignment. The
LCD screen shows SAT as the selected device in both cases.
I have macros set up that map Shift/n to Devn for n = 1,2,...,7. These turn the shifted digit keys 1
through 7 into device selection keys for my seven devices. There is more on shift actions in the next
section.
Dev2 = T_DEV4, V_DEV2.
A = Dev2, M_DEV1.
